Chapter 16
Measurement
within the CMMi
This chapter discusses the general topic of measurement within the CMMI. This
chapter serves as an introduction to our next three chapters about measurement:
Chapter 17, ???A Boatload of Metrics???; Chapter 18, ???Statistical Process Control???; and
Chapter 19, ???A High Maturity Perspective.??? Chapter 9, ???Alignment of Multiple
Process Improvement Initiatives,??? also discussed measurement by describing an
overall Measurement Program.
The CMMI has increased its focus on measurement by creating the Measurement
and Analysis process area (PA), emphasizing measurement within the Engineering
process areas, and expanding the importance of high-maturity concepts in
Level 4 and Level 5. We discuss each of these areas and summarize the decisions
organizations make that lead to success or failure when implementing measurement
programs.
the Measurement and Analysis Process Area
Organizations that used the family of CMMs learned that measurements need to
be aligned to business objectives to provide benefit, used regularly to justify effort
and cost, well defined so people could understand and use measurements correctly,
and communicated in an unbiased manner.
